BAIL-JOINT.

1 0 all w hem it may concern:

Be it known that I, J osnrrr ZYGMAN, citizen of Poland, residing at Greenwich, in the county of l airiield and State of Connecticut, have invented certain new and useful Improvements in Rail-Joints, of which the following is a specification.

This invention relates to rail joints and it has for an object to provide a simple arrangement of parts whereby the ends of the rails may be securely fastened together in a manner to prevent the fastening means from becoming loosened accidentally.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawin s, and to the appended claims in which t e various novel. features of the invention are more particularly set forth.

Figure 1 of the drawings is a plan view showing a pair of separated rail ends constructed according to the invention.

Fi 2 is a side view thereof.

Fig. 3 is a transverse vertical section with the rail ends joined, this view being taken at the point indicated by the line 3-3 in Fig. 2.

Fig. 4 is an end view of the locking bolt.

Fig. 5 is a fragmentary longitudinal section of the bolt, showing the releasing key in engagement therewith.

In the drawings the reference numerals 10 and 11 indicate adjacent rail ends, and 12 the ties. In constructing my improved rail joint the rail end 11 is formed with a projecting tongue which comprises a base-element 13 forming an extension of the base flange of the rail but flattened on its top surface as well as on its bottom surface. The

. tongue also comprises a somewhat thickened this thickened portion extending downwardly and outwardly from the side edges of the tread to the side edges of the base TE: recess in the rail end 10 comprises a check-out 18 on the bottom thereof to receive the baseflange portion 13 of the tongue on Specification of Letters Patent.

rail 11. From this check-out 18 the thicl ened rail end 11 is slotted upwardly as at 19 to form a recess adapted to receive the web portion 14, this recess having lateral offsets 20 at its inner end which accommodate the lugs 15.

To hold the assembled rail ends against vertical displacement I provide a pair of longitudinally movable locking bolts 22 which are accommodated in sockets or re cesses such as 23 in the thickened web element 16 of the rail 10, the tongue on rail 11 havlng registering recesses such as 24 in the end face thereof into which said bolts are adapted to project, the bolts being normally urged into said recesses by coiled expansion springs such as 25 located in the sockets 23 and bearing against the rear ends of the bolts 22.

To enable the bolts 22 to be completely drawn into the sockets 23 when the rail ends are being assembled or disassembled I form in the rear end of each bolt a recess 26 which is partially covered by a slotted end piece 27, this end piece presenting a pair of intersecting slots 28 whereby a T-headed key 29 may be inserted into the recess 26 and, upon being given a partial turn, engage the end piece 27 and so enable the bolt to be withdrawn from the socket 24 by pulling on the key against the spring 25. Suitable slots 30 lead into the recesses 23 from the rear ends of the web members 16 for the insertion of the key 29.

It is believed that the manner of use and operation of my improved rail joint will be readily understood from the above description.

Having thus described my invention what I claim as new and desire to protect by Letters Patent of the United States is as follows:

1. A pair of rail ends having interlocking elements preventing longitudinal displacement, and a bolt carried in a longitudinal socket in one rail end and projecting into a registering longitudinal socket in the other rail end.

2. A pair of rail ends having interlocking elements preventing longitudinal displacement, and a bolt carried in a longitudinal socket in one rail and projecting into a registering longitudinal socket in the other rail end, and a coiled expansion spring inserted in said first socket behind said bolt.

3. A pair of rail ends one of which has nal socket in one rail end and projectinginto a registering longitudinal socket in the other rail end, and a coiled expansion spring inserted in said first socket behind said bolt, said bolt having a recess in one end, a slotted head covering said recess and adapted to be engaged by a key to withdraw the bolt co1npletely into the first socket.

In testimony whereof I have ailixed my signature.

JOSEPH ZYGMAN.
